Product Description:
The MHD115B-035-NG1-BN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It delivers regulated torque and speed for industrial automation tasks that require repeatable positioning, such as pick-and-place robots, indexing tables, and feeder drives. By integrating feedback and a liquid-ready stator housing, the motor supports high cycle rates while fitting into liquid-cooled machine frames.
Its continuous stall capability reaches 50.0 Nm, indicating the torque the rotor can sustain indefinitely without overheating when locked. The enclosure carries a IP65 rating, so dust ingress is blocked and low-pressure water jets cannot reach live parts. A liquid cooling jacket draws heat directly from the stator, allowing higher RMS load and quieter cabinet operation. Position feedback is provided by a digital servo feedback (HSF) encoder, which supplies high-speed signal cycles for tight velocity loops. Reliable service is maintained throughout an ambient range of 0 to 40 °C, and no output derating is specified within that span. Insulation class F, relative position detection, and a connector on side B complete the electrical profile.
For static axis security, the integrated brake clamps the shaft with 70.0 Nm of torque when power is removed, helping hold vertical loads during emergency stops. The resolverless optical system detects rotor position within ±0.5 angular minutes, which supports contouring applications that demand tight orientation tolerance. Mechanical integration is simplified by a centering pilot of 180 mm and a square mounting flange that measures 192 mm across, aligning the motor with standardized gearbox and frame interfaces. A plain shaft with a sealing ring, a permissible storage range of −20 to +80 °C, and deployment up to 1000 m altitude supplement the installation data.
